Assessment of Primary and Metastatic Brain Tumor Hypoxia With Fluoromisonidazole, FDG and Water

Study Purpose

Purpose of Study This exploratory clinical study will investigate FMISO (fluoromisonidazole) in patients with

  • (1) newly diagnosed primary malignant brain tumors (WHO [World Health Organization] Grade III or IV glial-based tumors) who have not had a complete surgical resection and by contrast MRI (Magnetic resonance imaging) have residual tumor > 1.0 cm in diameter and will be receiving radiotherapy or (2) newly diagnosed brain metastasis (> 1.0 cm in diameter who will be receiving radiotherapy.
The ability to accurately assess tumor hypoxia and accurately determine the amount/degree of tumor hypoxia could potentially change patient management once validated as tumor hypoxia is known to be associated with a poor prognosis [Eyler 2008].

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

The patient must have a newly diagnosed primary malignant brain tumors (WHO Grade III or IV glial-based tumors) and not have had a complete surgical resection and by contrast MRI (obtained within 14 days prior to the FMISO study) 2. Patients must be 18 years or older for inclusion in this research study. 3. Patients must document their willingness to be followed until death or time of progression. 4. All patients must sign a written informed consent and HIPAA authorization in accordance with institutional guidelines. 5. Female patients who are not postmenopausal or surgically sterile will undergo a serum pregnancy test prior to the research PET scans. 6. Pre-treatment laboratory tests for patients receiving [18F]FMISO must be performed within 21 days prior to study entry.

Exclusion Criteria:

1. Patients with known allergic or hypersensitivity reactions to previously administered radiopharmaceuticals. 2. Patients who are pregnant or lactating or who suspect they might be pregnant. 3. Adult patients who require monitored anesthesia for PET scanning. 4. Patients who are too claustrophobic to undergo MRI or PET imaging. 5. Patients who cannot undergo MRI imaging due to MRI exclusion criteria

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Malignant Brain Tumors (Primary and Metastatic) Despite significant advances in the understanding of brain tumor biology and genetics as well as improvements in surgical techniques, radiotherapy administration, and chemotherapy methods, many brain tumors remain incurable. Many brain tumors are highly infiltrative neoplasms, and are therefore unlikely to be cured by local treatments such as surgery, focal radiotherapy, radiosurgery or brachytherapy. Rationale and Goals of Study The preliminary efficacy of the radiopharmaceutical, 1H-1-(3-[18F]-fluoro-2-hydroxy-propyl)-2-nitro-imidazole [18F]-fluoromisonidazole, [18F]FMISO, FMISO (fluoromisonidazole), a radiopharmaceutical that directly assess tumor hypoxia using Positron Emission Tomography(PET) will be assessed. This preliminary/exploratory clinical study will investigate [F-18]FMISO in 30 evaluable patients with newly diagnosed primary brain tumor or brain metastasis. We expect that up to 35 -40 total patients may be enrolled in this study. This will assure that 30 evaluable patients (patients who have complete imaging results and blood metabolism data available for data analysis). In certain patients the blood metabolism data is not acceptable for final analysis typically due to difficulty in drawing it rapidly enough due to the vein collapsing during the rapid sampling required. When possible we will also correlate FMISO uptake with the typical in-vitro test used to assess proliferation, Ki-67 (protein) and other experimental assessments of hypoxia. This correlation will be made whenever possible in those patients where tumor tissue is obtained as part of standard care. OBJECTIVES: Primary Objective of Study

  • - Synopsis The primary objective of this study is to determine the association of FMISO PET (positron emission tomography) uptake (hypoxic volume [HV]), highest tumor:blood ratio [T/Bmax]), FDG ([18F]-2 fluoro-2-deoxy-d-glucose) uptake, and tumor blood flow/perfusion determined with H2O (water) and MRI and correlate these variables with overall survival (OS) and time to progression (TTP) in participants with newly diagnosed primary brain tumors or brain metastases.
The Hypotheses to be Tested. Three exploratory hypotheses will be studied. These include: 1. The first hypothesis to be tested is that increased FMISO PET uptake (hypoxic volume [HV], highest tumor:blood ratio [T/Bmax]) is correlated with a shorter overall survival and a shorter time to progression. An exploratory evaluation assessing combinations of PET imaging variables such as hypoxic volume [HV], highest tumor:blood ratio [T/Bmax], FDG-SUV, FDG quantitative parameters and blood flow as well as MR (magnetic resonance) perfusion and blood volume will be assessed to see if they correlate with survival and time to progression. 2. A second hypothesis to be tested is that FMISO is safe and non toxic in the dose administered in this study in patients with primary and metastatic brain tumors. This will be assessed in the first 10 patients enrolled in the study. Even though there have been numerous published studies using FMISO in humans in several different tumor types little human safety data has been published. Laboratory tests (except urinalysis) will be repeated at approximately 24 hours in the first 10 and compared to the screening values. 3. A third exploratory hypothesis to be tested is that FMISO uptake (hypoxic volume [HV], highest tumor:blood ratio [T/Bmax]) will correlate with increased FDG uptake and possibly with reduced blood flow/perfusion as determined with H215O PET imaging and MRI
